Biography
Hroerekr Ringslinger was born in 665, said to be the son of the god Hodur; he was the father of Jutish chief Horwendill and the grandfather of Hamlet, the legendary prince of Shakespearean fame. Hroerekr became the jarl of Sjaelland (Zealand) in 700, and he would conquer Courland (in Latvia), Wendland (the Pomerania region of northern Germany and Poland), and Sweden for Sjaelland. It is unknown if Hroerekr was the father of Randver and Harald Wartooth, as some Norse sagas claim, but Harald succeeded Hroerekr as jarl of Sjaelland in 729.
